From mellow yellow to white hot! Selma Blair shows off her different styles as she switches day look for nighttime glamour

And yesterday Selma Blair showed off both those sides as she switched from a cute and girly daytime look to a white hot, glamorous nighttime look.

Selma was seen earlier in the day looking cute in a yellow patterned sundress, teamed with a pair of matching flip flops and pastel pink bag, before opting for a sexy white strapless dress as she attended the Hollywood FX Summer Comedies Party later in the day.

The 40-year-old actress also changed
up her hair and make-up - going for a loose ponytail and fresh-faced
look earlier in the day, before opting for a chic up 'do and burgundy
lipstick as she posed up on the red carpet.

Selma also teamed her glamorous evening outfit with a pair of black peeptoe heels and thin gold bracelets.

In a recent interview, Selma said she has 'two sides' to her character, explaining: 'Just as my CV has light and dark sides, I suppose there are two
sides to my own character.

Is that my good side? Selma primped and posed for photographers on the blue carpet at the event

'I go from being hugely popular and
entertaining to really not. I'm not a manic depressive, but I can really
go to the dark side.'

However, Selma also revealed she is looking forward to the future, and is excited about where her career is going.

She added to The Observer Magazine: 'I am hopeful again. I want a good life and
a great career more than I ever have. I don't know that I actually
believed I deserved one until now.'

Other stars to attend last night's FX party in Los Angeles included Charlie Sheen, who looked in good spirits despite having to deny claims that he had 'trashed' a New York hotel room earlier in the week.

Russell Brand also made an appearance at the event, larking around as he posed for photographers on the blue carpet.

As he attended the party, his estranged wife Katy Perry was promoting her new documentary film, Katy Perry: Part Of Me.

In the documentary, Katy, who split from Rock Of Ages star Russell in December after just 14 months of marriage, said that although he thought he was 'the one', she admitted that work commitments got in the way.

Here come the boys: Russell Brand and Elijah Wood also attended the party

She said: 'I thought to myself, "When
I find that person that's going to be my life partner, I won't ever
have to choose [between the partner and my career]. They won't be
threatened or have weird motives." Then I started to realise, that's not
true.'

Katy's forthcoming 3D movie features
footage shot around the time she split from Russell, including scenes
where she is crying on a bed, and she has previously revealed she wanted
to include the clips to show people they can bounce back from their
difficulties.

She said: 'I think if you were to see
the movie and it was completely avoided, you'd think, "Hmm that's
strange, I know something else happened in her life last year."

'So I wanted to handle it delicately
with the most integrity I could and show, "Yeah I'm going through the
same situation that half of America goes through and somehow I landed on
my feet, so you don't have to lay down and die like you think."

'Just because you're in the spotlight doesn't mean you get to dodge the curveballs - they're actually bigger.'
